摘要
为探究日照辐射对混凝土外栏板的影响,建立了有限元分析模型,分析在日照辐射作用工况下混凝土外栏板的温度和受力状况。分析结果表明,由于外栏板正晒面和背晒面受到日照辐射强度不同,不同表面温度存在差异,内部存在温度梯度,栏板产生附加变形和应力,栏板内钢筋亦产生了不可忽视的应力。根据分析结果,从设计、施工、养护方面提出了混凝土外栏板施工质量控制的建议。
For research the influences of the solar insolation to the concrete outsider fence-slab,set up the FEA model to analysis the temperature and mechanical situation under the case of solar insolation.The analytical results indicates that,there is a difference of temperature between the surface on the fence-slab front and back to the solar insolation because of the difference of intensity of solar insolation;additional deformation and stress will caused by the temperature gradient in the slab,the steel bar in fence-slab also shows stress not be ignored.Advices from the aspect of design,construction and curing for constructional quality controlling of the concrete fence-slab were given based on the analytical results.
